Common Mode Chokes Procurement Notes

Verify the exact suffix 'B' against official Murata documentation to confirm pin configuration and mechanical dimensions. Confirm RoHS compliance status directly with the manufacturer or authorized distributor. Check for end-of-life notices as some listings indicate scheduled obsolescence. Ensure the vertical package style matches the target PCB layout requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when a 1.8 mH inductance at 1.7 A is required for common mode noise reduction in AC power lines. The vertical through-hole format suits designs requiring specific board height constraints or manual assembly processes. Verify that the 250 VDC rating meets the system's electrical isolation and operating voltage needs.
